Make your banking app an everyday companion

When you’re looking for transaction data enrichment tools and their features, six vendors usually come up: Tapix, Tink, Ethoca, Salt Edge, Fiserv, and Plaid. Most comparison posts treat them as interchangeable API swaps. They are not. They sit at different layers of the stack, they solve different problems, and picking the wrong one means paying for capabilities you do not need while missing the ones you do. This article walks through what each tool actually does, what it does not, and how to match them to the problem you are trying to solve.

When a customer taps their card, the bank's issuer system receives a tightly structured but surprisingly thin bundle of card network transaction data. The fields are standardised, the values are constrained, and most of what an end user expects to see in their app - clean merchant names, logos, recognisable categories, exact shop locations - is simply not in the message. Everything from statement clarity to credit decisioning is built downstream of this raw payload, which makes the gap between what arrives and what a customer needs the single most consequential data problem in retail banking.

The EU's revised Consumer Credit Directive (CCD2 for short) is about to change the rules for consumer lending and BNPL across Europe. By November 2026, lenders will need to prove that borrowers can actually afford what they're signing up for. That puts transaction data at the centre of every credit decision.
